Thanks, looks like we got the same issue copy pasted between str_offsets (bug
#34383), rnglists (bug #34385) and loclists (bug #34386).

libdw: Check there are any header bytes in rnglists
We tried to read the rnglists header length and only then checked if
there were any bytes left. Make sure to check there are at least 4
bytes for the initial unit length.
* libdw/libdwP.h (__libdw_cu_ranges_base): Check before initial
unit_length read.
